Geography of The United Kingdom

Main article: Geography of the United Kingdom

The topography of the UK

The total area of the United Kingdom is approximately 243,610 square kilometres (94,060 sq mi). The country occupies the major part of the British Isles^[98] archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and some smaller surrounding islands. It lies between the North Atlantic Ocean and the North Sea with the south-east coast coming within 35 kilometres (22 mi) of the coast of northern France, from which it is separated by the English Channel.^[99] As of 1993 10% of the UK was forested, 46% used for pastures and 25% used for agriculture.^[100] The Royal Greenwich Observatory in London is the defining point of the Prime Meridian.

The United Kingdom lies between latitudes 49° to 61° N, and longitudes 9° W to 2° E. Northern Ireland shares a 360-kilometre (224 mi) land boundary with the Republic of Ireland.^[99] The coastline of Great Britain is 17,820 kilometres (11,073 mi) long.^[101] It is connected to continental Europe by the Channel Tunnel, which at 50 kilometres (31 mi) (38 kilometres (24 mi) underwater) is the longest underwater tunnel in the world.^[102]

England accounts for just over half of the total area of the UK, covering 130,395 square kilometres (50,350 sq mi).^[103] Most of the country consists of lowland terrain,^[100] with mountainous terrain north-west of the Tees-Exe line; including the Cumbrian Mountains of the Lake District, the Pennines and limestone hills of the Peak District, Exmoor and Dartmoor. The main rivers and estuaries are the Thames, Severn and the Humber. England's highest mountain is Scafell Pike (978 metres (3,209 ft)) in the Lake District. Its principal rivers are the Severn, Thames, Humber, Tees, Tyne, Tweed, Avon, Exe and Mersey.^[100]

Ben Nevis, in Scotland, is the highest point in the British Isles

Scotland accounts for just under a third of the total area of the UK, covering 78,772 square kilometres (30,410 sq mi)^[104] and including nearly eight hundred islands,^[105] predominantly west and north of the mainland; notably the Hebrides, Orkney Islands and Shetland Islands. The topography of Scotland is distinguished by the Highland Boundary Fault—a geological rock fracture—which traverses Scotland from Arran in the west to Stonehaven in the east.^[106] The faultline separates two distinctively different regions; namely the Highlands to the north and west and the lowlands to the south and east. The more rugged Highland region contains the majority of Scotland's mountainous land, including Ben Nevis which at 1,343 metres (4,406 ft) is the highest point in the British Isles.^[107] Lowland areas, especially the narrow waist of land between the Firth of Clyde and the Firth of Forth known as the Central Belt, are flatter and home to most of the population including Glasgow, Scotland's largest city, and Edinburgh, its capital and political centre.

Wales accounts for less than a tenth of the total area of the UK, covering 20,779 square kilometres (8,020 sq mi).^[108] Wales is mostly mountainous, though South Wales is less mountainous than North and mid Wales. The main population and industrial areas are in South Wales, consisting of the coastal cities of Cardiff, Swansea and Newport, and the South Wales Valleys to their north. The highest mountains in Wales are in Snowdonia and include Snowdon (Welsh: Yr Wyddfa) which, at 1,085 metres (3,560 ft), is the highest peak in Wales.^[100] The 14, or possibly 15, Welsh mountains over 3,000 feet (914 m) high are known collectively as the Welsh 3000s. Wales has over 1,200 km (750 miles) of coastline. There are several islands off the Welsh mainland, the largest of which is Anglesey (Ynys Môn) in the northwest.
Northern Ireland accounts for just 14,160 square kilometres (5,470 sq mi) and is mostly hilly. It includes Lough Neagh which, at 388 square kilometres (150 sq mi), is the largest lake in the British Isles by area.^[109] The highest peak in Northern Ireland is Slieve Donard in the Mourne Mountains at 852 metres (2,795 ft).^[100]

Climate

Main article: Climate of the United Kingdom

The United Kingdom has a temperate climate, with plentiful rainfall all year round.^[99] The temperature varies with the seasons seldom dropping below −11 °C (12 °F) or rising above 35 °C (95 °F).^[110] The prevailing wind is from the south-west and bears frequent spells of mild and wet weather from the Atlantic Ocean,^[99] although the eastern parts are mostly sheltered from this wind—as the majority of the rain falls over the western regions the eastern parts are therefore the driest.^{[citation needed]} Atlantic currents, warmed by the Gulf Stream, bring mild winters; especially in the west where winters are wet and even more so over high ground. Summers are warmest in the south-east of England, being closest to the European mainland, and coolest in the north. Heavy snowfall can occur in winter and early spring on high ground, and occasionally settles to great depth away from the hills.^[111]

Administrative divisions

Main article: Administrative geography of the United Kingdom

Administrative units of the United Kingdom

Each country of the United Kingdom has its own system of administrative and geographic demarcation, which often has origins that pre-date the formation of the United Kingdom itself. Consequently there is "no common stratum of administrative unit encompassing the United Kingdom".^[112] Until the 19th century there was little change to those arrangements, but there has since been a constant evolution of role and function.^[113] Change did not occur in a uniform manner and the devolution of power over local government to Scotland, Wales and Northern Ireland means that future changes are unlikely to be uniform either.

The organisation of local government in England is complex, with the distribution of functions varying according to the local arrangements. Legislation concerning local government in England is decided by the UK parliament and the Government of the United Kingdom, as England does not have a devolved parliament. The upper-tier subdivisions of England are the nine Government office regions or European Union government office regions.^[114] One region, Greater London, has had a directly elected assembly and mayor since 2000 following popular support for the proposal in a referendum.^[115] It was intended that other regions would also be given their own elected regional assemblies but the rejection of a proposed assembly in the North East region, by a referendum in 2004, stopped this idea in its tracks.^[116] Below the region level England has either county councils and district councils or unitary authorities and London which consists of 32 London boroughs. Councillors are elected by the first-past-the-post system in single-member wards or by the multi-member plurality system in multi-member wards.^[117]

Local government in Scotland is divided on a basis of 32 council areas, with wide variation in both size and population. The cities of Glasgow, Edinburgh, Aberdeen and Dundee are separate council areas as is the Highland Council which includes a third of Scotland's area but just over 200,000 people. The power invested in local authorities is administered by elected councillors, of which there are currently 1,222^[118] and are each paid a part-time salary. Elections are conducted by single transferable vote in multi-member wards that elect either three or four councillors. Each council elects a Provost, or Convenor, to chair meetings of the council and to act as a figurehead for the area. Councillors are subject to a code of conduct enforced by the Standards Commission for Scotland.^[119] The representative association of Scotland's local authorities is the Convention of Scottish Local Authorities (COSLA).^[120]

Local government in Wales consists of 22 unitary authorities. These include the cities of Cardiff, Swansea and Newport which are unitary authorities in their own right.^[121] Elections are held every four years under the first-past-the-post system.^[122] The most recent elections were held in May 2008. The Welsh Local Government Association represents the interests of local authorities in Wales.^[123]
Local government in Northern Ireland has, since 1973, been organised into 26 district councils, each elected by single transferable vote. Their powers are limited to services such as collecting waste, controlling dogs, and maintaining parks and cemeteries.^[124] On 13 March 2008 the executive agreed on proposals to create 11 new councils and replace the present system.^[125] The next local elections were postponed until 2011 to facilitate this.^[126]

Dependencies

Main articles: British Overseas Territories and Crown Dependencies

British Overseas Territories are indicated in red, Crown Dependencies in blue, and the United Kingdom in green.

The United Kingdom has sovereignty over seventeen territories which do not form part of the United Kingdom itself: fourteen British Overseas Territories^[127] and three Crown Dependencies.^{[citation needed]}
The fourteen British Overseas Territories are: Anguilla; Bermuda; the British Antarctic Territory; the British Indian Ocean Territory; the British Virgin Islands; the Cayman Islands; the Falkland Islands; Gibraltar; Montserrat; Saint Helena, Ascension and Tristan da Cunha; the Turks and Caicos Islands; the Pitcairn Islands; South Georgia and the South Sandwich Islands; and the Sovereign Base Areas on Cyprus.^[128] British claims in Antarctica are not universally recognised.^[129] Collectively Britain's overseas territories encompass an approximate land area of 667,018 square miles (1,727,570 km²) and a population of approximately 260,000 people.^[130] They are the remnants of the British Empire and several have specifically voted to remain British territories (Bermuda in 1995 and Gibraltar in 2002).

The Crown Dependencies are British possessions of the Crown, as opposed to overseas territories of the UK.^[131] They comprise the Channel Island Bailiwicks of Jersey and Guernsey in the English Channel and the Isle of Man in the Irish Sea. Being independently administered jurisdictions they do not form part of the United Kingdom or of the European Union, although the UK government manages their foreign affairs and defence and the UK Parliament has the authority to legislate on their behalf. The power to pass legislation affecting the islands ultimately rests with their own respective legislative assemblies, with the assent of the Crown (Privy Council or, in the case of the Isle of Man, in certain circumstances the Lieutenant-Governor).^[132] Since 2005 each Crown dependency has had a Chief Minister as its head of government.
